Diagnostic Test

WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.

CHECK IF RELATED TCM DTCS ARE PRESENT
1. With the scan tool, read DTCs
  Are there any TCM Power Input DTCs present also?
  
  Yes
  - Refer to DIAGNOSIS AND TESTING and perform the appropriate diagnostic procedure(s).
  No
  - Go To 2
CHECK FOR LOSS OF PRIME DTC
1. With the scan tool, check for other DTCs.
  Is the DTC P0944 present also?
  
  Yes
  - Refer to the DIAGNOSTIC CODE INDEX and perform the appropriate diagnostic procedure(s).
  No
  - Go To 3
CHECK TO SEE IF P083B IS CURRENT
1. With the scan tool, view DTCs.
  Is the status Active or is the Starts Since Set counter 2 or less for this DTC?
  
  Yes
  - Go To 4
  No
  - Go To 8
PCM AND WIRING
1. Turn the ignition off to the lock position.
2. Remove the Ignition Switch Feed fuse from the TIPM.
  CAUTION:
  Removal of the Ignition Switch Feed fuse from the TIPM will prevent the vehicle from being started in gear.
  
  WARNING:
  The Ignition Switch Feed fuse must be removed from the TIPM. Failure to do so can result in possible serious or fatal injury.
3. Install the Transmission Simulator (special tool #8333B, Simulator, Transmission) and the Electronic Transmission Adapter kit.
  NOTE:
  Check connectors - Clean/repair as necessary.
4. Ignition on, engine not running.
5. With the Transmission Simulator, turn the Pressure Switch selector to LC.
6. With the scan tool, monitor the LC Pressure Switch state while pressing the Pressure Switch Test button on the Transmission Simulator.
  Did the LC Pressure Switch state change?
  
  Yes
  - Replace the Transmission Solenoid/TRS Assembly in accordance with the Service Information.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 5
(T81) LC PRESSURE SIGNAL CIRCUIT OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C1 harness connector.
3. Disconnect the Transmission Solenoid/TRS Assembly harness connector.
4. Measure the resistance of the (T81) LC Pressure Signal circuit between the appropriate terminal of the PCM C1 harness connector and the Transmission Solenoid/TRS Assembly harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (T81) LC Pressure Signal circuit for an open.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 6
(T81) LC PRESSURE SIGNAL CIRCUIT SHORTED TO GROUND

1. Measure the resistance between ground and the (T81) LC Pressure Signal circuit.
  Is the resistance below 5.0 Ohms?
  
  Yes
  - Repair the (T81) LC Pressure Signal circuit for a short to ground.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 7
(T81) LC PRESSURE SWITCH SENSE CIRCUIT SHORTED TO VOLTAGE

1. Ignition on, engine not running.
2. With the scan tool in the TIPM, actuate the TCM output.
3. Measure the voltage of the (T81) LC Pressure Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T81) LC Pressure Signal circuit for a short to voltage.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Replace and program the Powertrain Control Module in accordance with the Service Information. With the scan tool perform Quick Learn.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set the DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 62TE VERIFICATION TEST. Refer to 62TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
